Question

What is the relationship between guard cells and stomata in plants?

Guard cells open and close the stomata to regulate the rate of transpiration.

Guard cells protect the stomata from insects and other pests.

Guard cells store carbon dioxide for later use by the stomata.

Guard cells absorb light energy from the Sun for use by the stomata.

Answer 1

Guard cells open and close the stomata to regulate the rate of transpiration.

Answer 2

Guard cells use osmotic pressure to open and close stomata, allowing plants to regulate the amount of water and solutes within them. In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis . Critical in this process is the stoma.
